Hi community.
The VMA05 user manual states “For use with Arduino Due”. The Due’s input pins are 3,3V and are not 5V tolerant. But on the VMA05 schematic I see that the digital inputs get their high voltage from the 5V through a LED and a 470R resistor. I guess the LED cause a voltage drop to 3.5V and together with the 470R that might be safe to work. Am i right?
